KOOTION 10 Pack 4GB Flash Drive 4gb USB 2.0 Flash Drives USB Drive Jump Drive Bulk Thumb Drive Swivel Memory Stick Black

Purchased this 10 pack as a pen testing solution. They are working so far, but writing to the product and conversion to bootable image drives was incredibly slow. Total write time for an image file (ISO) of 16GB was 32 minutes. Not great if you are in a hurry! Port used was USB 3.0, and this device is USB 2.0. This item was not up to the speed of the USB 2.0 spec, claiming up to 480MB/s. In my writing speed test, I wrote a 16gb ISO file. This took an incredibly long time, at an average write speed of 9.7MB/s. The speed decreased marginally, but steadily, as the write process continued. I might recommend for multiple smaller file solutions. Perhaps office documents to home, or schoolwork to home. In contrast, my tests say this product is not up to larger file work like ISO images.

So far, so good .... have had for two months and used four of the ten without problems. It is getting harder to find 1GB USB drives for a fair price - but they are perfect for music for plugging into my vehicle or just attach to my computer to hear certain genre ... 1GB is the perfect size. Easy to use and simply to open and close - just slide the sleeve around the USB. The speed of transfer is NOT fast - but acceptable. I havent had any problem with the cover coming free or detaching (someone apparently did). The sleeve is blank and easy to write on. It had no logo on either side (like the picture demonstrated). I also use them for transferring multiple pdfs and docx files of active projects as well as for transferring files between machines. Although limited to 1 GB (by choice), they do the job and work well for transporting files.

With these flash drives I add a short lanyard to add a touch of color and value added when I deliver my products to my customers

I use these everyday in doing CM Consulting Business

This was a good deal, they work great and seem to last as well.

I do a lot of recording of songs by year. These are perfect for me to put 125 or more songs on the drive for each year.

Works well no problems

Transferring DVD (audio and video) for family members. Utilized 5 to date. No problems.

Something I disliked was that when the usb was plugged in it was difficult for the computer to detect. Though it still will detect it as long as you move it a little, was worth the price though.

I have used the kootion USB sticks multiple times in the past. I bought this size to save designs from my embroidery machine.
